- Recall due to unusually high oil consumption
- 2,577 vehicles affected in Germany
- Engine damage and safety risks possible
At the turn of the year 2025 to 2026, Honda is coming under pressure with a sensitive technical issue. A possible manufacturing defect has been identified in the inline four-cylinder engine of the CB 1000 (SP) Hornet, which can lead to significantly increased oil consumption. If this goes unnoticed, there is a risk of serious damage to the engine with corresponding safety risks.
Recall already underway in the USA
The National Highway Traffic Safety Administration in the USA has been dealing with the problem since mid-December 2025. An official recall for the Honda CB 1000 (SP) Hornet has been initiated there. According to the agency, 452 motorcycles manufactured between September 30, 2024, and August 22, 2025, are affected. Dealers have already been informed, and written notification to vehicle owners is scheduled to begin on February 16, 2026.
Cause: unusually high oil consumption
Based on current knowledge, the 150+ hp inline four-cylinder engine may experience significantly increased oil consumption. Possible causes include manufacturing defects or excessive tolerances on the pistons and piston rings. Oil consumption is said to be several hundred milliliters per 1,000 kilometers, which is significantly higher than normal.
Risk to connecting rod bearings and engine mechanics
If the falling oil level is not checked regularly and compensated for in good time, insufficient lubrication may occur. Connecting rod bearings are particularly affected, as they wear out much faster when there is a lack of oil. This can lead to serious engine damage and even complete engine failure.
Safety implications: Risk of falling and fire hazard
A stalling engine can cause the rear wheel of the Honda CB 1000 (SP) Hornet to lock up. This results in an increased risk of falling. In addition, the US authority points out a possible fire hazard if leaking oil or fuel comes into contact with hot components, especially in the area of the exhaust system.
Situation in Germany: 2,577 vehicles affected
As of January 8, 2026, no corresponding entry had been recorded in the recall database of the Federal Motor Transport Authority. However, upon inquiry, Honda confirmed that 2,577 vehicles in Germany are affected by the recall. A spokesperson for Honda Motor stated that the process for damage assessment and repair is currently being determined. Affected customers will be informed in writing of all relevant details.
Scope of repairs still open
It is not yet clear how extensive the technical measures will be. It is possible that the affected engines will be overhauled with new pistons and piston rings, or that entire engines will be replaced. Specific information on the type and duration of the repairs is not currently available.
Other models not currently affected
It remains to be seen whether other models with a similar four-cylinder design could be affected. These include the announced but not yet available CB 1000 F and CB 1000 GT models. Honda has stated that these motorcycles are not yet on the market and that it will respond appropriately to any potential problems.
Oil consumption is not a completely new issue
The affected inline four-cylinder engine is based on an earlier supersport engine from the CBR 1000 RR Fireblade. Increased oil consumption was already discussed in practice with the Fireblade SC59 model from 2008 to 2016. Whether there is a direct technical connection remains unclear.
